The inventors of the present disclosure have found that a display defectoccurs due to displacement between a TFT substrate and a CF substrate ina liquid crystal curved display having a curved display surface.Specifically, when the TFT substrate and the CF substrate are bonded toeach other and bent in a process of manufacturing the liquid crystalcurved display, tensile and compressive stresses are applied to the TFTand CF substrates, and magnitude of the displacement (displacementamount) between the TFT substrate and the CF substrate varies accordingto a stress distribution in a display area, whereby color mixture orlight leakage occurs to visually recognize display unevenness. FIG. 15is a view illustrating a simulation result of the displacement amountthat occurs when the display panel in which the TFT substrate and the CFsubstrate are bonded to each other is bent with a curvature radius of500 mm. At this point, the displacement amount is illustrated when thelaterally long display panel is bent in a lengthwise direction(crosswise direction) while right and left ends of the display panel arefixed. As illustrated in FIG. 15, the displacement amount is small in acentral portion and the right and left ends of the display panel, andthe displacement amount is large in an area between the central portionand each of the right and left ends of the display panel. The simulationresult shows that the display unevenness becomes conspicuous in the areahaving the large displacement amount.

In curved display 1 of FIG. 2, a tensile stressis applied to glass substrate 101 constituting a thin film transistorsubstrate (TFT substrate 100), and a compressive stress is applied toglass substrate 201 constituting a color filter substrate (CF substrate200). In curved display 1 of FIG. 3, the compressive stress is appliedto glass substrate 101 constituting TFT substrate 100, and the tensilestress is applied to glass substrate 201 constituting CF substrate 200.Although described in detail later, liquid crystal layer 300 is disposedbetween TFT substrate 100 and CF substrate 200, and TFT substrate 100and CF substrate 200 are fixedly bonded to each other using sealingmaterial 60 with liquid crystal layer 300 sandwiched therebetween.

Referring to FIG. 1, a plurality of data lines 11 extending in a columndirection and a plurality of gate lines 12 extending in a row directionare provided in display panel 10. Thin film transistor (TFT) 13 isprovided in an intersection portion of each data line 11 and each gateline 12. Each data line 11 and each gate line 12 are formed into acurved shape (convex shape) according to a bending direction of curveddisplay 1. As used herein, the bending direction means a directionparallel to the display surface, and for example the row direction orthe column direction. For example, in the case where the bendingdirection is the row direction (see FIG. 4), data line 11 is formed intoa linear shape while gate line 12 is formed into the curved shape.

In the case where the bending direction is the column direction (seeFIG. 5 described below), data line 11 is formed into the curved shapewhile gate line 12 is formed into the linear shape.

Based on an externally-input power supply voltage and the control signalinput from control circuit 40, gate line driving circuit 30 generates agate signal (gate voltage), and outputs the gate signal to each gateline 12.

FIG. 6 is a plan view illustrating a configuration example of pixel 14of display panel 10. FIG. 7 is a sectional view taken along line A-A inFIG. 6, and FIG. 8 is a sectional view taken along line B-B in FIG. 6. Aspecific configuration of pixel 14 will be described below withreference to FIGS. 6 to 8.

Referring to FIG. 6, an area partitioned by two adjacent data lines 11and two adjacent gate lines 12 corresponds to one pixel 14. Thin filmtransistor 13 is provided in a plurality of pixels 14 respectively. Thinfilm transistor 13 includes semiconductor layer 21 formed on insulator102 (see FIGS. 7 and 8) and drain electrode 22 and source electrode 23,which are formed on semiconductor layer 21 (see FIG. 6). Drain electrode22 is electrically connected to data line 11, and source electrode 23 iselectrically connected to pixel electrode 15 via through-hole 24.

Pixel electrode 15 including a transparent conductive film such asIndium Tin Oxide (ITO) is formed in each pixel 14. Pixel electrode 15includes a plurality of openings (slit), and is formed into a stripeshape. There is no limitation to a shape of an opening. one commonelectrode 16 made of a transparent conductive film such as ITO is formedover the whole display area. One common electrode 16 is shared by aplurality of pixels 14. An opening (corresponding to a dotted-line boxin FIG. 6) is formed to electrically connect pixel electrode 15 andsource electrode 23 to each other in an area where common electrode 16overlaps through-hole 24 and source electrode 23 of thin film transistor13.

As illustrated in FIG. 7, display panel 10 includes TFT substrate 100,CF substrate 200, and liquid crystal layer 300 sandwiched between TFTsubstrate 100 and CF substrate 200.

In TFT substrate 100, gate line 12 (see FIG. 8) is formed on glasssubstrate 101, and insulator 102 is formed so as to cover gate line 12.Data line 11 (see FIG. 7) is formed on insulator 102, and insulator 103is formed so as to cover data line 11. Common electrode 16 is formed oninsulator 103, and insulator 104 is formed so as to cover commonelectrode 16. Pixel electrode 15 is formed on insulator 104, andalignment film 105 is formed so as to cover pixel electrode 15. In glasssubstrate 101, polarizing plate 106 is bonded to a surface (rearsurface) of a glass substrate, the surface facing a backlight device 50(a side opposite to a liquid crystal layer 300 side).

A plurality of light transmission parts 202 and black matrix 203 areformed in CF substrate 200. A plurality of light transmission parts 202are disposed according to a plurality of pixels 14, and transmitspredetermined light. Black matrix 203 blocks the light transmission. Forexample, the plurality of light transmission parts 202 include a redlight transmission part, a green light transmission part, and a bluelight transmission part. In the red light transmission part, a redcolored component (red portion) is formed to transmit red light. In thegreen light transmission part, a green colored component (green portion)is formed to transmit green light. In the blue light transmission part,a blue colored component (blue portion) is formed to transmit bluelight. As to an array of the light transmission parts (coloredcomponents), a longitudinal stripe array may be adopted such that thered light transmission part, the green light transmission part, and theblue light transmission part are repeatedly arrayed in this order in therow direction while the light transmission parts having the identicalcolor are arrayed in the column direction. Alternatively, a crosswisestripe array may be adopted such that the red light transmission part,the green light transmission part, and the blue light transmission partare repeatedly arrayed in this order in the column direction while thelight transmission parts having the identical color are arrayed in therow direction. Black matrix 203 is formed in an area (boundary) betweenlight transmission parts 202 adjacent to each other in the row directionand the column direction. In a portion extending in the column directionof black matrix 203, a position of center line ml in a width directioncoincides with a position of a center line in a width direction of dataline 11. In a portion extending in the row direction of black matrix203, a position of center line n1 in a width direction coincides with aposition of a center line in a width direction of gate line 12. Aspecific configuration of black matrix 203 will be described later.

Overcoat layer 204 is formed so as to cover light transmission part 202and black matrix 203. Alignment film 205 is formed on overcoat layer204. In glass substrate 201, polarizing plate 206 is bonded to a face(surface) on a display surface side (the side opposite to the liquidcrystal layer 300 side). The laminated structure of each partconstituting pixel 14 is not limited to the structure in FIGS. 7 and 8,but a known structure can be applied.

Liquid crystal 301 is sealed in liquid crystal layer 300. Liquid crystal301 may be a negative liquid crystal having a negative dielectricanisotropy or a positive liquid crystal having a positive dielectricanisotropy. Alignment film 105, 205 may be an alignment film subjectedto a rubbing alignment process or a light alignment film subjected to alight alignment process.

Thus, curved display 1 has a configuration of a crosswise field schemein which an electric field substantially parallel to TFT substrate 100and CF substrate 200 is applied to liquid crystal layer 300. Forexample, curved display 1 has a configuration of an IPS (In-PlaneSwitching) scheme. Curved display 1 is not limited to the crosswisefield scheme. For example, curved display 1 may have a configuration ofa VA (Vertical Alignment) scheme.

A method for driving curved display 1 will briefly be described below. Ascanning gate voltage (gate-on voltage, gate-off voltage) is suppliedfrom gate line driving circuit 30 to gate line 12. A video data voltageis supplied from data line driving circuit 20 to data line 11. When thegate-on voltage is supplied to gate line 12, thin film transistor 13 isput into an on state, and the data voltage supplied to data line 11 istransmitted to pixel electrode 15 through drain electrode 22 and sourceelectrode 23. A common voltage (Vcom) is supplied from common electrodedriving circuit (not illustrated) to common electrode 16. Commonelectrode 16 overlaps pixel electrode 15 with insulator 104 interposedtherebetween, and an opening (slit) is formed in pixel electrode 15.Therefore, liquid crystal 301 is driven by an electric field from pixelelectrode 15 to common electrode 16 through liquid crystal layer 300 andthe opening of pixel electrode 15. Liquid crystal 301 is driven tocontrol transmittance of light transmitted through liquid crystal layer300, thereby displaying the image. The method for driving curved display1 is not limited to the above method, but a known method can be adopted.

Curved display 1 has a configuration suppressing the display qualitydegradation, such as the display unevenness, which is caused by thedisplacement between TFT substrate 100 and CF substrate 200.Specifically, for example, the width of black matrix 203 is set to adifferent value according to the area where the displacement occurs. Thespecific configuration of black matrix 203 according to the presentexemplary embodiment will be described below.

FIG. 9 is a plan view illustrating an entire configuration of blackmatrix 203. Black matrix 203 is formed into a lattice shape as a whole,and at least a part of black matrix 203 overlaps data line 11 and gateline 12 in a plan view. An area surrounded by black matrix 203constitutes light transmission part 202. A case where the bendingdirection of curved display 1 is the row direction (see FIG. 4) is givenas an example. In curved display 1, compared with portions located atboth ends in the row direction (first direction), a portion located atthe center in the row direction (first direction) is curved so as to beconvex on the display surface side or the rear surface side. FIG. 9illustrates a central portion which is a center portion in the rowdirection of the display area (display screen), a left end portion thatconstitutes a left end in the row direction when the display screen isvisually recognized, a right end portion that constitutes a right end inthe row direction when the display screen is visually recognized, a leftarea which is an area between the central portion and the left endportion, and a right area which is an area between the central portionand the right end portion in the whole area of black matrix 203.

As illustrated in FIG. 9, black matrix 203 which is the light shieldingpart includes a plurality of column portions 203 a (second lightshielding portions) extending in the column direction (second direction)and a plurality of row portions 203 b (first light shielding portions)extending in the row direction (first direction). The plurality ofcolumn portions 203 a include first end light shielding portion a1 andsecond end light shielding portion a2. First end light shielding portiona1 constituting the left end portion of black matrix 203 is disposed onone end side in the row direction. Second end light shielding portion a2constituting the right end portion of black matrix 203 is disposed onthe other end side in the row direction. The plurality of row portions203 b include third end light shielding portion a3 and fourth end lightshielding portion a4. Third end light shielding portion a3 constitutingone end portion in the column direction of black matrix 203 is disposedon one end side in the column direction. Fourth end light shieldingportion a4 constituting the other end portion in the column direction ofblack matrix 203 is disposed on the other end side in the columndirection of the display surface. The plurality of column portions 203 aalso include central light shielding portion a5 disposed on the centralside in the row direction.

FIG. 10 illustrates a configuration in which a part of the left area isenlarged in the entire configuration of black matrix 203 in FIG. 9. FIG.11 illustrates a configuration in which a part of the right area isenlarged in the entire configuration of black matrix 203 in FIG. 9.

In the left area of FIG. 10, black matrix 203 is set such that width Wbof column portion 203 a extending in the column direction orthogonal tothe bending direction varies according to the displacement amount,although width Wb of column portion 203 a represents a length in the rowdirection. Specifically, black matrix 203 is set such that width Wb1 ofcolumn portion 203 a closest to the area where the displacement amountis maximized (the maximum displacement area in FIG. 15) becomes largest,and width Wb of column portion 203 a becomes narrower toward the leftend portion and central portion from the maximum displacement area. Thatis, the width of column portion 203 a of black matrix 203 is set so asto satisfy Wb1>Wb2>Wb3>Wb4 and Wb1>Wb5>Wb6>Wb7. Column portions 203 a ofblack matrix 203 are disposed at equal intervals (pitch P1) in the rowdirection. The position of center line ml of the width of column portion203 a coincides with the position of the center line of the width in therow direction of data line 11. Therefore, the width of lighttransmission part 202 (opening) becomes Wc1<Wc2<Wc3 and Wc4<Wc5<Wc6.

In black matrix 203, the widths of row portions 203 b extending in thebending direction (in this case, the row direction) are set so as to beequal to one another. Row portions 203 b of black matrix 203 aredisposed at equal intervals (pitch P2) in the column direction. Theposition of center line n1 of the width in the column direction of rowportion 203 b coincides with the position of the center line of thewidth in the column direction of gate line 12.

The right area in FIG. 11 and the left area in FIG. 10 are symmetricalwith respect to the central portion (see FIG. 9). That is, black matrix203 is set such that width Wb of column portion 203 a varies accordingto the displacement amount. Specifically, black matrix 203 is set suchthat width Wb1 of column portion 203 a closest to the area where thedisplacement amount is maximized (the maximum displacement area in FIG.15) becomes largest, and width Wb of column portion 203 a becomesnarrower toward the right end portion and central portion from themaximum displacement area. That is, the width of column portion 203 a ofblack matrix 203 is set so as to satisfy Wb1>Wb2>Wb3>Wb4 andWb1>Wb5>Wb6>Wb7. Column portions 203 a of black matrix 203 are disposedat equal intervals (pitch P1) in the row direction. The position ofcenter line ml of the width of column portion 203 a coincides with theposition of the center line of the width of data line 11. Therefore, thewidth of light transmission part 202 (opening) becomes Wc1<Wc2<Wc3 andWc4<Wc5<Wc6.

In black matrix 203, the configuration of row portion 203 b extending inthe bending direction (in this case, the row direction) is identical tothat in FIG. 10.

FIG. 12 is a view illustrating a sectional configuration of three pixels14 adjacent to one another in the row direction. FIG. 12 illustrates apart of black matrix 203 in FIG. 10. As illustrated in FIG. 12, columnportion 203 a closest to the area where the displacement amount ismaximized (the maximum displacement area in FIG. 15) has the maximumwidth Wb1, and width Wb of column portion 203 a becomes narrower towardthe left end portion and central portion. Column portion 203 a overlapsdata line 11 in a plan view. In the above configuration, black matrix203 has the width according to the displacement amount, so that thelight leakage caused by the displacement between TFT substrate 100 andCF substrate 200 can be suppressed while a numerical aperture is notdegraded more than necessary.

FIG. 13 is a graph illustrating a relationship between the width ofblack matrix 203 and the displacement amount. FIG. 13 illustrates widthWb of column portion 203 a of black matrix 203 in the case where thebending direction is the row direction. For example, widths Wb of thecolumn portions 203 a is t1 and equal to one another in the centralportion, right end portion, and left end portion, where the displacementhardly occurs and the displacement amount is minimized. On the otherhand, widths Wb of the column portions 203 a is t2 (t2>t1) in the area(the right and left maximum displacement areas) where the displacementeasily occurs and the displacement amount is maximized. In the right andleft areas, a ratio of a change in the displacement amount from themaximum displacement area to the end portion (the right end portion orthe left end portion) is larger than a ratio of a change in thedisplacement amount from the maximum displacement area to the centralportion. For this reason, preferably the width of column portion 203 aof black matrix 203 is set according to the ratio. For example, in FIG.10, width Wb2 of column portion 203 a disposed on the left side ofcolumn portion 203 a having width Wb1 is narrower than width Wb5 ofcolumn portion 203 a disposed on the right side of column portion 203 ahaving width Wb1 (Wb2<Wb5), and width Wb3 of column portion 203 adisposed on the left side of column portion 203 a having width Wb1 isnarrower than width Wb6 of column portion 203 a disposed on the rightside of column portion 203 a having width Wb1 (Wb3<Wb6). Similarly, thewidth of column portion 203 a is set so as to be Wb4<Wb7. FIG. 13illustrates width Wb4, Wb7 of column portion 203 a by way of example. Atthis point, it is assumed that distance D1 from the center of themaximum displacement area to the center of width Wb4 is equal todistance D2 from the center of the maximum displacement area to thecenter of width Wb7. Thus, when the widths of the right and left columnportions 203 a having the same distance from the center of the maximumdisplacement area are compared to each other, the width of columnportion 203 a on the end side is narrower than the width of columnportion 203 a on the central side.

FIG. 14 is a graph illustrating another relationship between the widthof black matrix 203 and the displacement amount. FIG. 14 illustrateswidth Wb of column portion 203 a of black matrix 203 in the case wherethe bending direction is the row direction, similarly to FIG. 13. Asillustrated in FIG. 14, width Wb of column portion 203 a is t1 in thecentral portion, and width Wb of column portion 203 a is t2 in the rightand left maximum displacement areas (t2>t1). In the right and leftareas, width Wb of column portion 203 a is kept constant from themaximum displacement area to the end portion (the right end portion orthe left end portion). In the example of FIG. 14, the display qualitydegradation caused by a luminance difference between the right and leftmaximum displacement areas and the right or left end portion can besuppressed because the luminance in the end portion is prevented fromincreasing more than necessary. Thus, width Wb of column portion 203 ain the maximum displacement area is wider than width Wb of columnportion 203 a in the central portion, and is equal to width Wb of columnportion 203 a in the end portion (the right end portion or the left endportion).

The above example illustrates the case where the bending direction isthe row direction. In the case where the bending direction is the columndirection, similarly, the width of row portion 203 b of black matrix 203may be set so as to vary according to the displacement amount (see FIG.15). Regardless of the bending direction, both the width of columnportion 203 a and the width of row portion 203 b of black matrix 203 maybe set so as to vary according to the displacement amount (see FIG. 15).

In the above example, the position of center line ml of the width in therow direction of column portion 203 a of black matrix 203 coincides withthe position of the center line of the width in the row direction ofdata line 11. Alternatively, the center position of center line m1 ofthe width in the row direction of column portion 203 a of black matrix203 may be displaced from the center position of the center line of thewidth in the row direction of data line 11. For example, in curveddisplay 1 of FIG. 3, the width of column portion 203 a of black matrix203 disposed on the left area is set such that the position of centerline m1 of the width in the row direction of column portion 203 a isdisplaced to the central portion side with respect to the position ofthe center line of the width in the row direction of data line 11, andthe width of column portion 203 a of black matrix 203 disposed on theright area is set such that the position of center line m1 of the widthin the row direction of column portion 203 a is displaced to the centralportion side with respect to the position of the center line of thewidth in the row direction of data line 11. A relationship between theposition of center line m1 of the width in the row direction of columnportion 203 a of black matrix 203 and the position of the center line ofthe width in the row direction of data line 11 may be set inconsideration of a visual recognition direction or a size of the displaypanel.

A case where the curveddisplay 1 of the present disclosure is used as the automotive devicewill be described in detail below.

A blind angle of the driver may occur at the pillar. The safedriving of the driver can be assisted if the exterior informationcorresponding to the blind angle is projected to the pillar. Therefore,wide-view angle ensuring display 2011 is preferably disposed in thepillar in order to project the exterior information on the vehicle.There is no particular limitation to the use of automotive device 500 aslong as automotive device 500 is mounted on vehicle 2001 to display thevideo.

Main bodycomponent 501 includes frame body 510 disposed in a periphery of curveddisplay 1, and display surface S1 that displays the video of curveddisplay 1 is exposed from opening 503 surrounded by frame body 510.

As illustrated in FIG. 17, frame body 510 of main body component 501includes first frame edge portion 511 and third frame edge portion 513,which are disposed opposite to each other in the column direction(second direction), and second frame edge portion 512 and fourth frameedge portion 514, which are disposed opposite to each other in the rowdirection (the bending direction or the first direction). First frameedge portion 511 and third frame edge portion 513 correspond to a placeextending in the row direction (first direction), that is, the rowdirection (first direction), and second frame edge portion 512 andfourth frame edge portion 514 correspond to a place extending in thecolumn direction (second direction), that is, the row direction (firstdirection). As can be seen from FIG. 19 described later, first frameedge portion 511 corresponds to third end light shielding portion a3 inthe periphery of curved display 1, more particularly is located alongthird end light shielding portion a3, second frame edge portion 512corresponds to first end light shielding portion a1 in the periphery ofcurved display 1, more particularly is located along first end lightshielding portion al, third frame edge portion 513 corresponds to fourthend light shielding portion a4 in the periphery of curved display 1,more particularly is located along fourth end light shielding portiona4, and fourth frame edge portion 514 corresponds to second end lightshielding portion a2 in the periphery of curved display 1, moreparticularly is located along second end light shielding portion a2.

FIG. 18 is a side view of automotive device 500. As illustrated in FIG.18, first frame edge portion 511 includes first bent area 511 a that iscurved in the row direction (first direction) so as to project toward adirection identical to curved display 1. In the example of FIG. 18,curved display 1 is curved such that the portion located at the centerin the row direction becomes convex from the rear surface side towardthe display surface side. Therefore, first bent area 511 a is alsocurved such that the portion located at the center in the row directionbecomes convex from the rear surface side toward the display surfaceside. Accordingly, a risk that a foreign material or dirt entering froma boundary between curved display 1 and frame body 510 can be reducedbecause at least a part of frame body 510 disposed in the periphery ofcurved display 1 is curved along curved display 1.

As can be seen from FIGS. 9 and 18, in the row direction (firstdirection), first bent area 511 a is located in an area between firstend light shielding portion al and second end light shielding portiona2.

First frame edge portion 511 includes second bent area 511 b that isdisposed closer to first end light shielding portion al than first bentarea 511 a. Second bent area 511 b is curved in the row direction (firstdirection) so as to project toward a direction opposite to first bentarea 511 a. That is, second bent area 511 b is curved such that aportion located at the center in the row direction becomes convex fromthe display surface side toward the rear surface side.

FIG. 19 is a plan view illustrating black matrix 203 and frame body 510in curved display 1. FIG. 20 is a sectional view taken along line D-D inFIG. 19. As illustrated in FIGS. 19 and 20, each of first frame edgeportion 511, second frame edge portion 512, third frame edge portion513, and fourth frame edge portion 514 partially covers a peripheralarea of curved display 1 in a plan view. In particular, first frame edgeportion 511 overlaps third end light shielding portion a3 in a planview, second frame edge portion 512 overlaps first end light shieldingportion a1 in a plan view, third frame edge portion 513 overlaps fourthend light shielding portion a4 in a plan view, and fourth frame edgeportion 514 overlaps second end light shielding portion a2 in a planview. Frame edge portions 511 to 514 are formed up to the positions thatoverlap corresponding end light shielding portions a1 to a4 in a planview, which allows the light leakage occurring from four corners ofcurved display 1 to become inconspicuous.

In the example of FIG. 19, first frame edge portion 511 protrudes ontothe central side of curved display 1 beyond third end light shieldingportion a3 in a plan view, and second frame edge portion 512 protrudesonto the central side of curved display 1 beyond first end lightshielding portion a1 in a plan view. Length L1 in which first frame edgeportion 511 protrudes from third end light shielding portion a3 in aplan view is longer than length L2 in which second frame edge portion512 protrudes from first end light shielding portion al in a plan view.

FIG. 20 illustrates a layer configuration of curved display 1. Asillustrated in FIG. 20, curved display 1 includes front plate 400 formedinto a curved shape, and display panel 10 is bonded to front plate 400with bonding agent 450 interposed therebetween. In the configuration,display panel 10 can be held in front plate 400 in a curved state.

FIG. 21 illustrates a modification of the layer configuration in FIG.20, and illustrates a case where first frame edge portion 511 is notprovided in frame body 510. In the example of FIG. 21, frame body 510 ofmain body component 501 includes second frame edge portion 512 locatedalong first end light shielding portion a1 in the periphery of curveddisplay 1 and fourth frame edge portion 514 located along second endlight shielding portion a2 in the periphery of curved display 1, secondframe edge portion 512 overlaps first end light shielding portion al ina plan view, and fourth frame edge portion 514 overlaps second end lightshielding portion a2 in a plan view.

FIG. 22 illustrates a modification of the arrangement of first bent area511 a in a section corresponding to FIG. 20. In the example of FIG. 22,first frame edge portion 511 includes first bent area 511 a, and flatarea 511 c that is disposed in an area away from first end lightshielding portion al (see FIG. 19) than first bent area 511 a. Firstbent area 511 a is located closer to first end light shielding portional than to central light shielding portion a5 (see FIG. 19) in theplurality of column portions 203 a. More particularly, first bent area511 a is located away from first end light shielding portion a1 by adistance smaller than a half of a distance from first end lightshielding portion a1 to central light shielding portion a5. In theexample of FIG. 22, like the example in FIG. 18, first frame edgeportion 511 may further include second bent area 511 b, and second bentarea 511 b may be disposed at a position away from a display side thanfirst bent area 511 a.
